The Wellington Sludge Minimisation Facility - Te Whare Wai Para Nuku is a once in a generation transformative infrastructure project aimed at providing a long-term, sustainable, and resilient approach to the treatment of Wellington City's wastewater biosolids.

The project is a world-class facility, the first of its type in New Zealand, and uses a mixture of pressure, heat and biological processes to reduce the amount of sewage sludge created through the normal wastewater treatment process and turn it into a safe, reusable product. The reduction in sludge volumes of up to 80%, not only reduces the volume of sludge entering the landfill, but also reduces carbon emissions by capturing biogas and utilising it as a fuel source to provide both heat and power in the treatment facility.
